To all fwhofmlz't may concern: Y v

`Be it knOWnthaVLCHARiEs PALMER, a citizen of the United States, residing in the city ofNewarli, vcountyof Essexfand Stater'of New Jersey^,have,invented certain 'newgand' useful? Improvements in Door`` Locks, of which vthe following yisa-full, clear, :and eiact'description, such asjiwill enable others skilledl inthe art to which it pertains to \m`ake,fconstruct, l and {use the 'f same, reference-'being had to the'accoxnpanying drawings, and to numeralsfof ref'- Yerence marked thereon, forming a ipart of this specification'.

`My invention relates to aV door flock lspetype wherein, the (door automatically o ens -1when my devices are pushed against; -f Y he object of vthe invention sthe rodu'ct'ionof 'al door vllock,which shall be'sunplegand' effectivelinffconstruction,' comparatively yi'n- -expensivein cost, and providedV with means pressure appliedagainst th'einner side of" an outwardly opening door, the locl'r necha- '-nismwould! be vreleased bysaid'fpressure, in-

- sists in certain n oveltiesofconstructionand istegad of by the lfisual turning movementpractised 'in the ease of the-usual knobflock.

yWithithi's end! inf view, my inventionfconlarrangements of p arts,f'as hereinafter set forth and pointed outin the'claims.-

' `While Y:the preferred form .of myy invenftionis Vlillufstrated in'y theV accompanying "minor changes f may be 'madeY without i' departingfromthe scopethere'of.

i Figurel1 represents a vertical vsectional .elevationI of ak doorprovided with `1 my irn.

:proved lock,` thelatch bolt housing and" the tionj -Fig- 2 representson an `enlargedscalefe. vertical sectional levation ofthe lat'ch'fbolt l and parts in theirnorm'al *locked positiongf 'i y latchboltanditshousingl bolt andY trigger intheirnormal locked pou siti'on.

In the drawings 1 v represents .the door 1frame','ra nd 2 the door hinged to the frame. An upright. rod -4 is movable vertically through a slotted housing 5 on the door.

'A lever 6 projects through a ,slot intoj'the housing to which it is intermediately pivotedas at 7. 1 The lever within the housing ment with said bifurcated end of the lever 6.

"When the external end of the lever` 6 is pushed toward the door, yits end within thel h'ousingfliftsfthe rod 4, and vice versa when fno oneisjy pushing against-- the lever,then `tl1e' weight ofthe rod 4 ofy the connected part returns thfelever 6 automatically into itsk original or normal positi`on, fas shown in "The'latch `lf3- clit 9tadj ustably secured tothe up er end of theupright rodv 4, by means of .a ook nut`3, is; 'slidably lo cated within a suitablev housing 10 `lattached Lto the upper part of the door.l` A similarhousing 1'1. is.at' tached to theflowe'r partof the doo'r,fin 1 which Vthe 'otherf or free end of. the` upright 'rod 4 is slidably suppOITld. The Klatchcboljt 1 9 shits upper 6nd,.' isfprevided iaith-prefer- Y ably,integralVv lateral .extensions 12 consti'- `t'uting thelintegral lool; boltgof `the latch b olt`9which is receivable into'a socket mem- -ber.14fwhichis screwedY to ythe topofth-e .the Y members, vone to receivethe lOCkIlg boltlo.- cated above and theother socket'member 15 locatedbelow, in thelloor or threshold which is vdesigned'to receive the free end of the upright rod 4. The upper end .of the latch'bolt 9` Ais preferably, provided witha cavity 16,

` and the front facev ofthe latchb'olt with an Yelongated slot' 17. Two'diametrically opposed slots V18 `are also provided in vthe sides of the latchbolt. to receive avstud 19 which passes 'through said diametrically .opposed slots 18,-'and"`the endsof which are secured inthe yhousingy 10,'as clearlyfindicated in the drawings. f

(A Stud '20 vpreferably rforrlnedaintegralz" uponthe rear inner face of the` latchbolt, eX- 'tends into thecavity 16. l

Pivotally mounted upon the studfg19r` weighted v'trigger 21. provided withan upper` outwardly projecting 'extension 22 terminating in the head 23; the lowerlend of said trigger being provided with a hooked shaped portion 24 designed to engage with and -be disengaged from the inwardly projecting stud 20.

The socket member 14 which is screwed to' the top of thedoor frame, preferably con- Vsists ofl a singlecasting comprising a supporting plate 25 from which rises a boxelike casing 26, provided with an open end, the central yportion of said supporting plate 25 being provided with ardownwardly extend- Y ing lug 27 the vinner surface of which is designed to be engaged by the head 23 of the trigger'21, as clearly indicated in the draw-y ings. vExtending downwardly from thel underside of the supporting plate 25, fare two ribbed holding lugs 28-28 designed torhave l holding and locking lengagement with the two lateral extensions 12, ofthe lock bolt, when the parts are inthe position. indicated inthe drawings', see Figs. 1 and 6, showing 'the door in locked position. y Y i These lugs 28-28,are located on the rear ofthe socket member and project vdown,-

box-like casin i The operation 'of the illustrated device will be apparent from what has already been said; namely, that when the'external en d of the lever 6` is'puslied toward the doorf'its 'Y vend within the housing lifts the rod 4 ,fand

the latch bolt -9, thereby VVdisengaging the 'lower free end of the rod 4, fromfthe socket member 15, located in the floor or'threshold,

and causes theend of the latch bolt r9 Vwith its f, 'lock bolt to enter the box-like casing 26, at the same time causing the'hooked shaped portion 24 of the trigger 21 Vto be hooked under the underside of the stud 20 in the cavityf'l VofV the latchV bolt 9,' see Fig. 3, whenthe lock A' Vbolt 13 has been moved into theboX-like casing 26, vand, the lateral extensions 12 of the lock `bolt will become disengaged from the holding lugs 28 of the socket member 14,

, and the lock bolt is therefore free tokpass out through the open end of the casing 26,

fand to be moved out of locking and holding position withV the socket member 14. By

l drawing.

closing theidoor,the parts are brought into locking position by means of the head' 23 of the trigger engaging with the downwardly whichcauses the hooked shaped portion 24 thereof, to become disengaged from the stud i 20, permitting the freelend of the rod to drop into thel socket member 15 in the floor, :and the lateral extensions 12 of the lock bolt lto drop `behindtlie lugs 28-,28 of thesocket member 14, as illustrated inF ig. 2 of the Experience has demonstrated that the organization above described is a highly efto withdraw the same member." ,A 1. Y V- 2. The lcombination-with a door and its icient one, land while I have shown the pre ferred embodiment of my present invention, I do notwish `to be limited to the exact details of construction shown and described,
